Put your thumb — or your mouse — on the tab at the start of the line and drag along it. Stray off the line or pull too hard and the tension meter climbs; lift off and it bleeds away, while the clock keeps running. It is the same game that is on Google Play, built from the same code, not a cut-down version.
What this page does and does not do
- Your score is not saved. Progress lasts until you close the tab — levels, badges and high scores all reset. The app keeps them on your device. That is the honest reason to install it rather than a feature we removed to make you.
- There are no ads here. Not as a favor: the ad network has no browser version, so there is nothing to show. The app on your phone carries one banner outside gameplay, and we would rather say that than let this page imply otherwise.
- Nothing is sold, and the game collects nothing. No in-app purchases, no currency, no account and no sign-in. The game itself stores nothing beyond the tab and sets no cookies of its own. This page does carry the same analytics as every other page on the site, which is described in the privacy policy; in the EEA, the UK and Switzerland it stays off until you accept the banner.

One font comes from Google. The game engine is
served from this domain rather than from Google’s CDN, which
is not the framework default and was changed deliberately. The
typeface is the exception: the browser fetches
Roboto from
fonts.gstatic.com. That is Flutter’s default when an app names no font of its own, and files are requested as glyphs are needed, so a screen we did not open could ask for another. Checked against this build on 9 September 2026 rather than assumed, and we spend a lot of this site asking other people to disclose things like that.
If it runs badly
It is about three megabytes the first time — measured as served, compressed, on 10 September 2026, and most of that is the rendering engine rather than the game. It also leans on the browser rather than the phone’s graphics chip, so an old laptop or a weak connection will feel it, and the first load is slower than the second because nothing is cached yet. The installed app has neither problem. There is more about the game, including what it costs and what it collects, on its own page.
